By the end
Explain what a price is, who is on the other side of a trade, and why "the market went up because of X" is usually a story rather than a measurement.

  • Market knowledge +12
  • Technical +4

A price is not a valuation. It is the level at which the most recent buyer and the most recent seller agreed to transact. It reflects the opinion of the marginal participant — the one who traded — not the average opinion of everybody holding the asset.

This matters because of how market commentary is written. When an index falls 1.2%, an explanation appears within minutes: a data release, a policy comment, a geopolitical event. The explanation is generated after the fact by matching the move to whatever news is nearest to hand. Sometimes it is right. It is almost never verified.

Example — The same news, two headlines

Inflation comes in above expectations. If the market falls, the headline reads "stocks slide on hot inflation print". If the market rises, the headline reads "stocks shrug off inflation as investors look through the data". Both are written from the same fact, and the direction is supplied by the outcome rather than by the analysis.

VILIQ handles this differently. When the market moves against the mechanical expectation for an event — a bad inflation surprise followed by a rally, say — it flags a market reaction anomaly rather than inventing a narrative to smooth it over. An unexplained move is information; a fabricated explanation is not.

  • Liquidity is how easily you can trade without moving the price. It is not constant, and it disappears fastest when you need it most.
  • The spread is the gap between the best buy and best sell price. It is a real cost, paid on entry and again on exit.
  • Volume tells you how much traded, not who was in control. Volume on a falling day is not automatically "selling".
  • A market that has not traded has no price, only a last price — which can be badly out of date for illiquid assets.

Common belief

"There were more sellers than buyers today, so the price fell."

What is actually true

Every trade has exactly one buyer and one seller, so the counts always match. What changes is urgency: prices fall when sellers are more willing to accept lower prices than buyers are to pay higher ones. The imbalance is in eagerness, not in numbers.

Glossary

Marginal participant
The buyer and seller who actually transacted, whose agreement sets the price.
Spread
The difference between the best available buy and sell price. A real, repeated cost of trading.
Liquidity
How easily an asset can be traded without moving its price.
Market reaction anomaly
When the market moves against the mechanical expectation for an event — worth flagging rather than explaining away.

Challenge — Audit a market headline

Find any market headline that explains a price move ("X fell on Y"). Write down the claimed cause, then list what evidence would be needed to actually establish that Y caused X. Finally, state at least one alternative explanation the headline did not consider.

What a good answer contains

  • Quotes or paraphrases a specific headline and its claimed cause
  • Names concrete evidence that would be required to establish causation
  • Offers a genuine alternative explanation, not a restatement
